This text is a continuation of my article where I explained the structure a Caché database. In this article, I described the types of blocks, connections between them and their relation to globals. The article was purely theoretical. I made a project that helps visualize the block tree - and this article will explain how it works in great detail.

Storage Management

We want to isolate the storage of our CCDAs from our HL7 V2 data, but keep them under the same namespace. From my understanding, I should create a new database then store those classes related to CCDAs in that database. Is this the correct approach?

I am looking for a database management tool I would have expected to find something like on the SMP website

Aim

show current database usage (ie size allocation) by database then table etc and allow continued drill down,

show information as a table, so can then sort by size to find the biggest item easily

also show it graphically

And then have ability to track and trend growth in size over time

identify a normal growth pattern

alert if variation (higher or lower) from normal based on recent trend

在Aix7.1上安装使用root用户安装cache2016.1.1.107,且在安装过程中创建cacheusr用户;更改操作系统上的cacheusr的umask后,通过数据库修改编译后的文件(如,js,csp等)在小机上查看权限不变(-rwxrw-r-- cacheusr cacheusr test.js)。

目的:通过数据库编译后的文件的other用户有读写权限。

mySQL data importer tool

Hi,

If you want to import data from a mySQL export file (exported with mysqldump), you will find here a little script that could help.

Only the INSERT commands in the sql file are executed into Caché. Indices are not computed for better performance.
%NOINDEX, %NOCHECK and %NOLOCK are generated on each INSERT line.

Currently, the file can not contain a "),(" pattern inside the values part of the INSERT command. If this is the case, the line is skipped. This feature may be implemented in the extractValuesList method.

Is the default language (i.e., $$$DefaultLanguage, which is used as the basis for localization with $$$Text/etc. at compile time) always "en" for new Caché installations, or could it be different? How is this determined? I don't see an option to select a language during Caché installation.

Also, is there a supported/preferred API for setting the default language? Looking at %occMessages.inc, one option would be:

Caché Monitor is a database\sql tool primarily for InterSystems Caché but can also connect to MS SQL Server, MS Access and more databases. Within Caché Monitors Server Navigator you see all available Namespaces on your Caché Servers. No need to know the name of the Namespace, no need to configure many many JDBC Connections by hand. Just click on the namespace and see all objects like tables, views, classes and more...

The object and relational data models of the Caché database support three types of indexes, which are standard, bitmap, and bitslice. In addition to these three native types, developers can declare their own custom types of indexes and use them in any classes since version 2013.1. For example, iFind text indexes use that mechanism.
